Introduction
CT1000 contactors are air switching components with arc breaking in ce-
ramic. They use a highly sophisticated principle of arc control, combining
the permanent-magnetic and electro-magnetic blow-out technique.
This allows practically unrestricted operation for all AC and DC voltages
and currents within the technical specification.
CT1015 contactors are designed for nominal voltages of 1,500 V.
CT1030 contactors are designed for nominal voltages of 3,000 V.
Due to the very high rated insulation voltage CT1030 contactors
can be used for peak voltages up to 5,000 V.
This manual refers to single pole contactors with a conventional
thermal current of 800 A. For single contactors for 400 A refer to
manual C20/04-M. For single contactors for 1,100 A refer to man-
ual C20/11-M.
CT1000 contactors provide excellent switching performance from very
small up to heavy loads.
CT1000 contactors are available for vertical and horizontal mounting.
CT1000 contactors have been designed and tested according to National
and International Railway Standards. Due to their unique features they
can also be used in a variety of industrial applications.
CT1000 contactors offer the following design-related advantages:
Compact, rugged design
2 voltage levels, several current levels
Double-break contacts, cadmium-free contact tips
1-, 2- (and 3-) pole versions
Easy maintenance:
o
Easy inspection of main contact tips, easy replacement of
main contacts
o
Easy replacement of arc chamber (upper module)
Drive system suitable for standard railway supply voltages and
tolerances. No economy circuit required for standard versions.
Drive systems for industrial applications on demand.
Insulation coordination:
o
Functional insulation for main circuit
o
Basic insulation between main circuit and protective earth
o
Reinforced insulation between main circuit and control
circuit / main circuit and auxiliary circuits
Long mechanical and electrical life
No regular maintenance required. Inspection intervals and exchange of
wear parts depending on specific application.
